RAILROAD-TIE.

Speciflcation of Letters Patent.

Patented Feb. 19, 1918.

Application led August 8, 1917. Serial No. 185,185.

To all 'whom it may concern.'

Be it known that I, ,PAUL lV. RonoHL, a citizen t the United States, residingnr at New Canaan, in the county of Fairfield and State of Connecticut, have invented certain new and useful Improverneixts in Railroad-Ties, of which the folle-dug is a specilication.

This invention relates to railwayties,a1id more lnlrl'iculariy to ira-tallie lies of holltnv Coi'istruotimi,

Une of the main objects of the invention is to provide a tie of Haq chgmetefstated of simple construction which may ou produced at relatively wel@ cost A further objet-.t is to provide a tie having aslot to receive securing bolts for fastening the plates for holding the rails in position on the tie, thisl tie being; further provided with a reinforcing member communicating with the slot and adapted to support the securing.' bolt and hold the same against rotation. Fur-ther objects will .appear from the detailed description.

In the drawings:

Figure l is a top vieu' of a tie coi'istrueted in accordance with the invention as applied.

Fig. 9. is a. longitiulinal central vertical section taken ilJiroupJ-h. the tio as applied.

Fig. 3 is an end if" of the tie.

Fig; 4 is 'a similar rie-rf of a modii'ied form. The tie. l c .itialiy rer, l cross section ha-vii walls 2- and 8, bottom wall irland top wall 5. This tie may be cast of any suitable material though I prefer to employ malleable iron casting. A slot (3 Ais rovided atthe center of the top Wall 5 and extends' the full length of the tie. This slot. ooinmui'iicates directly With the interior ot a. del'ierufling substantially U-s-haped 'member 7 formed integral with the top wall. '.lhis channel member-is adapted to slidably receive the square head 8 of a seeiiril'ig boit E) 'ii'isr-.rted into the Same with its shank' or stem projecting through slot (i. The channel i'neinber serves, in this manner, to secure the bolt against rotation and also to support it in proper position l with the Shania, portion thereof projecting inserted through suitable apertures through the plate, the usual seeurin nut bein threaded on each bolt above tie plate. plate l5 similar to plate 12 is provided on its under face with a series of serra-tions ivhich cooperate v vith the series 11 formed ou the tie., this plate being secured in posi- 1 ion by the bolts 9, the tu'o plates cooperating to secure the rail 1S on the'tie. I

.l'he securing bolts, when first placing the tie iu position, may be. readily inserted into the charmel member T' ignari each end of the tie. To permit insertion of: bolts after the. rails ler-ne been far-curati to the ties.A I provide. alii-led rectangular recesses l and 2-0 at the longitudinal center of the tie comxnunioat .inv with the slot 6. 'These recesses are of suicient size to4 permit ready insertion of a bolt head into the channel member 7, the bolts being freely movable toward either end of the tie after being thus` inserted into the channel member.

In the modified form shown in Fig. 4, the under or bottom Wall 4 of the tie is provided with a central longitudinally extending slot G correspondingV to slot 6 of the top wall of the tie. This slot G communicates directly 'with the interior of an upwardly extending channel member 2l formed integrally with. bottom Wall 4 corresponding to channel member 7. Channel member and slot cooperates to receive. the heads and shanlis of suitable securing bolts inserted into the same so as to retain these bolts and prevent rotation. thereof. This forni of tie is especially adapted for use'in eoiineetion with bridges, elevated railways., and similar struction; the. channel nu'finbgr '2l and .slot G providing means wherelo the tie may be quickly and easily scoort-:o to a struct-ure of this character.

A tie eonst-.ructeifl in this marmer, in. addition to being; very strong and relatively light, may be, lin'odueed at :.elatlrely small cost and is well able to withstand the vibration to 'which it is necessarily subjected. '.lo prevent distortion or lateral spreading of the tie under ,unusual loads or strains, suitable tie bolts 22 may be inserted through the side Walls 2 and 3,v these bolts being secured in position by nuts 23 threaded on to the same.

While lthis tie has been shown and described as used with rail securing 'plates of a specific form, it. will be understood that it may be equally well used 1n connection with securing members of various types, and I do not desire to in any way limit myself to the particular type of securing plate illustrated. It will be equal] evident that the tie can be of any length esired so as to be used for switches, crossings, and other purposes. 4

What I claim is: f

A hollow tie of'substantially rectangular cross section provided in its top and {bot- Y tom wall with longitudinally extending s1ots,. said slots extending the full lengt of the tie, said 'tie having an integral dgpending reinforcing channel memberfreemunicating directly said bottom wall.

In testimony whereof I ailx my signature in presence of two witnees.
